Successful scalping just takes years of patience and working with mixture of both S/R, volume, indicators, and using the Dome in regards to volume differences. Much of it is just noticing little sticks of price that accumulate at same areas on one minute bars. If anyone is truly interested in doing this, T-Notes are extremely good for it, as price waffles around so much more than ES, and I never risk more than a tick in T-Notes. Once you get good at reading the volume on the Dome and seeing when one side is so much more volume than other, and then starts to tighten up, got to pull the plug and take what market gives for profit. Have to work hard at it, nothing in life is easy, but rewards are huge when you develop the knack and seldom have losses. My mentor use to do 100-150 trades a day hitting 98% for 1-3 ticks, I had to stop doing that many trades 4.5 years ago, but I still manage to do a fair amount of trades, but target up to 8 ticks.
Best times to Scalp is 9:00 to 13:15 cdt and last 35 minutes. But after awhile, any time is good.
Often spikes in volume means reverse to me.
Highs/lows in price doesn't always have to form a pivot to have value.
